FASTENER.

Application filed August 13, 1921. Serial No. 491,911.

To all Vwhom. t may concern Be it known that I, BENJAMIN F. HUD- BELL, a citizen of the United States, and resident of Cambridge, in the county of .Middlesex State of /lassachusetts, have invented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains t0 improvements in fasteners. It is among the objects of -the invention to provide a fastener ofsuperior construction and appearance, and preferably one which may, if desired, be locked against separation 0f the parts by lateral strain between stud and socket.

In the drawings, which show a preferred form of one embodiment of my invention Figure 1 is a front'elevation of two pieces Aof fabric held together by a preferred forni of fastener;

Fig. 2 is a section on the line 2-2 of Fig. 1, being partly .in elevation; u

Fig. 3 is a front elevation of a preferred form of socket' illustrated vin Fig. 1;

v Fig.l 4 is a rear elevation of the socket illustrated in Fig. 3;

Fig. 5 is a section on the line 5-5 of Fig. 4 Y

,Fig 6 is a plan view of a modified form of socket; and

Fig. 7 is a section on the line 7-7 of Fig. 6.' y

Referring tothe drawings and t0 the preferred form of my invention selected for illustrative purposes, I have shown a studV including a head 6, a neck 7 and a base 8 secured by stitching 9 to thestud-carrying fabric 10. The preferred form of socket illustrated includes a casing having a plate 11, preferably circular as illustrated, and centrally apertured at 12 for passage of the head of the Stud therethrough. The casing contains the resilient means for gripping the head of the stud typified by the spring 13, providing jaw portions 14 and 15 intersect ing opposite sides of the aperture 12 in the socket casing. The socket casing may be parallelly ianged at 2O to contain and overlie the spring 13 and may be secured to the socket carrying fabric 21 by the stitches 22. In the preferred form of my invention illustrated, the socket casing adjacent the studreceiving aperture 12 therein is provided with a struck-up fiange 16 which, as illustrated, is preferably somewhat larger than the stud-receiving aperture so as to provide a lip 17 around all or portions of the studreceiving aperture which the head of the stud may overlie when engaged in the socket. The preferred form of my invention illustrated includes at one side of the stud-receiving aperture and in this doubled portion of the socket casing a notch 0r lateral extension 18 corresponding to the notch illustrated in United States Letters Patent to Fred S. Carr No. 1,865,022, issued January 11, 1921. The purpose of this notch is to provide a lock between stud and socket when under lateral strain in the direction of the notch, this lock,

however, preferably being insufficient to perf mit separation of stud and socket even when under some lateral strain pursuant to relative tipping between stud and socket in a direct-ion somewhat greater than the angle which is likely to be produced by the resolution of forces between stud and socket when under strain.

The struck-up flange or rim 16 serves the function normally served by the dome of fasteners in that it is slotted to permit passage therethrough of the jaw portions 14 and 15 of the spring 13, the portions of the flange 16 overlying such slots servingto hold down the jaw portions 14 and 15 of the spring against displacement when the head of the stud is entered in the socket, while permitting the spring jaws to yield as the stud isentered and to spring back into engagement with the neck of the stud after the latter is entered in the socket. In the preferred form` of my invention illustrated, the spring jaws 14 and 15 are not parallel but flare away from each other in the direction of the notch 18, thusl providing adjacent the notch 18 a flange of considerably greater strength than could be provided if the jaw portions were parallel. The flaring of the jaws 14 and 15 also serves to press or urge the nec-k of the stud toward the notch 18 when entered between the aws 14 and 15. The flange 16 preferably, as illustrated, terminates at or below the plane of the adjacent edge of the socket casing so that the flange does'not thicken the socket as a whole, as is usually the case where a dome is used. The flange 16 being spaced away from the stud-receiving aperture, permits the neck of the stud to engage over the adj acent edge of the socket without that resnlttion in Figs. fl-through 5, there are certain advantages appertaining to the modication senting afpart overlyingsaid spring means of my invention` illustratedin Figs. 6 and 7, wherein thestruckaip Harige or rim 16 is4 somewhat enlarged, ypreferably being made circular to provide.agreater. overhang over the jaw'portions oi the. spring and to provide a double thickness of metal at thefsides of the stud-receiving aperture as well `as at the ends thereof. f 1

It' will be understood that? changesinvolving omission, substitution, alteration and reversal of parts,- and .even changes inV the mode of operation, may be inadewithout departing [from: the,v scope ol: my` invention, whichv `is best'delined in the 4followingclaims yl. A fastener comprising, in combination,

a stud having a head and a neck and afsocket vincluding a casing presenting a stud-receiving aperture, areveisely flanged portion of the easing at the edge of said. aperture to presenta double thickness of metal and a smooth edge, springineans intersecting said aperture to grip the neck of said stud when entered therein, an upstanding iiange prewhile permitting stud-engaging and disengaging movement thereoffandta lateral extension ofsaid aperture within"said'upstand- 40- ing {iange to `providealock against undesired separation ofstud and socket kwhen'under lateral strain.

2'. A fastener comprising, in combination, a stud having-a head and aneckand a socket including a casingA providing a plate having a. .stud-.receiving aperture therethrough, and

v a. iiange formed integralwith said plate and surrounding in spaced relationship the studreceiving aperture in said plate, said ilaiige slotted toy lpermit passage therethrough of resilient studfengaging means.l v

3. -A `fastener comprising, in combination, a stud havinga headl and a' neck, a socket including a plate having. ajstud'freceiving aperture therein an'd=prov.i`di`ng a reversely bent lip surrounding said aperture and an upstanding flange slotted topermit, passage therethrough of astud-engagingj aw and a notch through said plate. and. said lip com# municating with said aperture.

4;. A fastener comprising, in combination, a stud `having a. head and a neck and a socket including a casing having a stud-receiving aperture at one side thereofl'andfanotchrin said casing communicatingwith said aperture to provide a lateral extension thereof,

kand a spring in said casing, said spring providing twojawportions intersecting oppo.- site sides of said stud-receiving aperture and inclined away from each other. in a-d-irection toward said notch whereby; the fheado'fisaid stud whenv entered inI said aperturemaybe urged toward. said notchv by said jaw. pori-z tions.A q

6. A socket for stud andasocket fasteners comprising, inl combination,` afcasingr- ,providing a plate having-a peripheral `flange and providing a `stud-receivingaperture therein, said stud-receiving aperture notched'y or extended atv one side', aspringlin said. casing, a flange surrounding tliefstiidfreceiving aperture in said casing aand guiding the A'studengaging portions of said spring, and a notchv communieatin-g withxsaid@ aperture, said "flange terminating adjacentfthelplane ot that sideoithe socket. toward-l which said flangeextendsand :providing an.l openlside throughwhich the head ofthe stud may pass when engaged with-thesocke't. i y
